did my swap about a week ago...been having problems...the headgasket isn't good, leaking oil...plus the radiator is foaming, and when driving...sometimes white/greyish smoke comes out of the tailpipe. when my friends and i did the swap...we added mobil1 5w30...4 quarts. Went for a test drive, and came back...the dipstick was low on oil so we added another one...it was halfway...the next day when i was going to travel back home...we added another one too. when driving i saw white smoke....and checked the sparkplugs yesterday....all was black, where the spark is at...and had bits of oil on it....also the sparkplug closest to the camgears had hella oil on it...and was black. Now i need your guys help...since this is my first swap....what does all this mean(what i mention above) and what do i need to do. also the dipstick is from a gsr...do i need a b16 dipstick? I know i need to replace the headgasket, and the sparks too, but give me some advice. the sparks are ngk platiums by the way...my motor is a jdm b16 w/ type r cams and type r intake manifold...w/ gsr distributor and throttlebody...by the way my car idles at 1 1/2 rpms...was told that it was the tps sensor....and my timing is off too.
